Who Says You Need Four Cores?

Power Consumption

At idle, it’s the AMD’s Athlon X2 4850e and 740G that serve up the lowest power consumption numbers. Stepping up to a quad-core Phenom X4 at the same frequency costs an extra 30 W. Intel’s Core 2 Duo E7200 falls in between the two, using nine more watts than the ultra-efficient 4850e.

Pour on the load, however, and power consumption gets a bit more interesting. The Intel chip actually uses the least power at 115 W. The Athlon X2 4850e jumps up to 127 W. And the Phenom X4 eats up 230 W total (from the wall, of course).

So, not only are there important price and performance considerations to factor into your buying decision, but power puts an twist on things as well. Dual-core processors are naturally going to use less energy at comparable frequencies. The difference can actually get pretty significant, though, once you start cranking up the workload.

  • Well. It seem like virtualisation was left out as consider multi-core is critical for running virtualise application.

    waste of time to read, its been known for years that you dont compare clock speeds (in this case, 2.53ghz) - you compare price points! Wheres an Intel Quad? or a lower end Intel like a E4600 etc? and after all that BS, why the cheap AMD board thats "$10 - $15 less" against that expensive ass intel board? pffftttt

    I completely don't get the point of the phenom 9850 in this review. Isn't this supposed to be a comparison of budget, workstation systems with dual core CPUs? Why put it in there? If you put a current Intel quad core in for consideration then it's power consumption would be high as well.

    What exactly are you trying to prove here? In any case. Any idiot knows that currently Intel's Dual core is the ideal processor. Currently of course.

    And what the hell were you thinking with the motherboard? A 740G? You even state in your conclusion that the 780G is a more fair comparison to the G45? Of course it is! Why did you even review the 740G then?

    I mean what a conflicting hodge podge of an article!

    If you haven't bought a new computer in 6 years don't do a review about your epic fail of picking computer parts. I mean your just embarrassing....

    If you give a million monkeys a typwriter, one of them will write a T.H article... Seriously, most of the readers of this site are well informed, this king of waffle is no good

    so quad isn't worth it now... what about in six years. just as Hyper Threading has kept his P4 going so long, going quad will have the same effect. Quad doesn't scale now, but in six years? dual core will seem like single core is now - quad core = new dual core. Just my two cents

    I currently run a Q6600 (3GZ OC) and it has done wonders for me. Take it I do a lot of Adobe Photoshop, gaming, coding, and generally have about 20-30+ windows open at one time which I would consider my "business" & "entertainment" use.

    If you add virtualization into the mix the quad core definitely has saved me. I don't experience any hiccups and now that I've migrated to 64 bit I've noticed a subtle gain in overall computing too.

    I think the highest I've hit on all my cores with extensive testing is 60-70%. This was running a few browser windows + 4 scanning programs at the same time and I did get some slow down due to my hard drive read/write speeds maxing out but nothing from the CPU. Which to me leaves plenty of room for what I actually do.

    Eventually when more software actually catches up to using 4 cores it'll be better utilized I suppose but for the most part I'm happy with it and I think you'll be happy with a dual or quad core.

    Running HL2:EP2 as a benchmark is pretty silly when its only single threaded

    Nothing surprising, interesting, or useful about this. Am I missing something, was the article incomplete and posted early? Just don't get it.
